by around 2010 parents will be able to genetically ensure their babies won't grow up to be fat or alcoholic, and by 2050 arrange to insert an extra gene into single-cell embryos within 24 hours of conception to make babies resistant to AIDS."-Lee M. Silver (Deenen) .
With the world's technology advancing, the human race is waiting for advances in medicine, but may not be ready for the complications that come with those advantages. The problem is not really with the advances in technology, but the possible risks that are involved with developing new medical research. Although vaccines are useful, they may not always be worth their development in the future.
Vaccines and their development can be seen through two sets of eyes, the group that is for vaccinations and those that are against it. For example, the development of the Hepatitis B vaccine has both pros and cons. The development of a vaccine for the Hepatitis B virus consists of taking the infected plasma out of the person and injecting synthesized (HBsAg) plasma into the infected person. In its favor, this does not only take out the bad plasma but it may encourage good plasma to start growing again. This is just an experimental treatment to develop a vaccine for Hepatitis B, but it is a step in the right direction. Another advantage is that by giving a person this vaccine, it may avoid liver cancer. Through many studies, conducted by doctors, says, "the relative risk of contracting liver cancer.is higher than the relative risk of lung cancer.being 100:1" (Nossal 95). It has been proven that Hepatitis B is a factor in the development of liver cancer. These are just a few of many advantages to vaccine development, now and in the future. .
However, there is a down side to these vaccinations. First of all, there is the money factor. These studies and developments of vaccines are very expensive. Therefore, some of the less fortunate people in the world may not have access to these vaccines.
